<h3 id="Asterisk13Function_PASSTHRU-Synopsis">Synopsis</h3>

<p>Pass the given argument back as a value.</p>

<h3 id="Asterisk13Function_PASSTHRU-Description">Description</h3>

<p>Literally returns the given <em>string</em>. The intent is to permit other dialplan functions which take a variable name as an argument to be able to take a literal string, instead.</p>

    <div class="aui-message hint shadowed information-macro">
                    <p class="title">Note</p>
                            <span class="aui-icon icon-hint">Icon</span>
                <div class="message-content">
                            
<p>The functions which take a variable name need to be passed var and not ${var}. Similarly, use PASSTHRU() and not ${PASSTHRU()}.</p>

                    </div>
    </div>

<p>Example: ${CHANNEL} contains SIP/321-1</p>

<p>${CUT(PASSTHRU(${CUT(CHANNEL,-,1)}),/,2)}) will return 321</p>
